Effect of Subcontracting on Construction Scheduling

摘要

The right sequence of construction works and their positioning in time-schedule are unavoidable prerequisites for a high-quality construction process. Often a prepared schedule has serious problems in ignoring the necessary technological sequence of works or, if the technological order is correct, due to a lack of flexibility in case of any unpredicted changes. The necessity of planning the construction process according to various limitations and changes, technological correlations and resources provides a challenge to create a model that would allow preparing flexible schedules for construction tasks. Such a model should take into account the conditions, limitations and possibility of changes for specific construction sites on a case-by-case basis, and thus planning correctly the share of subcontracting. The paper discusses the possibilities for preparing a construction schedule and the effect of subcontracting within it. Also, the initial conditions and parameters of the simulation model for evaluation of different management strategies are determined.
